  1. 26. Occupational exposure to particles in relation to chronic obstructive pulmonary disease and cardiovascular disease

    Författare :Karin Grahn; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Objective The working life is expanding with increased retirement ages as the population is aging, in Sweden but in also other parts of the world. However, workers with poor health might not cope with working in higher ages. LÄS MER

  3. 27. Novel Insights into the Oxidation of High Temperature Alloys - The Role of Environment, Microstructure and Reactive elements

    Författare :Nooshin Mortazavi Seyedeh; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reactive elements; nitridation; High temperature materials; nitrides; alumina; hydrides; microstructure; chromia; oxidation;

    Sammanfattning : The properties of materials can be deteriorated, when they react with an environment at high temperature and form various types of corrosion products, such as oxides and nitrides. In order to perform successfully at elevated temperatures, all these materials are required to be protected by a slow-growing, continuous and adherent surface oxide layer. LÄS MER

  4. 28. Measurement of primary DNA damage in individual cells from humans and mice using the alkaline single cell gel electrophoresis assay

    Författare :Hamid Vaghef; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; Farmaceutisk biovetenskap; Biopharmacy; Biofarmaci; arbets- och miljömedicin; Occupational and Environmental Medicine;

    Sammanfattning : Primary DNA damage is considered to be an important step in the development of tumours and itmay also serve as a biomarker of genotoxic stress. Measurement of DNA strand breaks in peripherallymphocytes can yield useful information about the suitability of these cells for biomonitoring purposesand subsequently risk assessment. LÄS MER

  5. 29. Impact of psychosocial factors on rheumatoid arthritis

    Författare :Louise Hedenstierna; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : In the field of rheumatology, the research has been successful in the understanding of the molecular mechanisms of the underlying pathophysiology of rheumatoid arthritis (RA). As a result of this, targeted treatments have been developed, resulting in a dramatic improvement of disease outcome. LÄS MER

  7. 30. Atmospheric Corrosion of Historic Lead Organ Pipes

    Författare :Annika Niklasson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Atmospheric corrosion; conservation strategies; formiate; historical organs; organ pipe corrosion; lead; oak wood; formic acid; acetic acid; acetate;

    Sammanfattning : The atmospheric corrosion of lead is investigated, with the aim to improve the understanding of the environmental degradation of historical organ pipes. Fieldwork is combined with laboratory investigations. The field studies included characterization of the organ environment and exposures of lead coupons. LÄS MER
